Harald Hårdtand: Kampen om de rene tænder (or Harold Hardtooth in The Fight for Clean Teeth) or simply "Colgate" for short, is an advergame platformer released in 1992 for the C64, Amiga and DOS. The game was developed by SilverRock Productions, a Copenhagen-based Danish company founded in 1988 and renamed in 1992 to Interactive Television Entertainment (ITE), best known for developing and producing the Hugo the Troll media franchise.

The soundtrack is short and sweet with only 3 tracks, or 4 if you count the unused title theme. The music was originally composed on C64 by Thomas Mogensen, a.k.a. (DRAX) of the demoscene group Vibrants. Additional support for sound effects and music for all three platforms was handled by Jens-Christian Huus (JCH) and Jesper Olsen (JO) of Vibrants, and Thomas Engel. Join us as we dive into the music of an advergame for the first but probably not last time.
